Sparco was the first to bring sport compression technology to motorsports, and continues to innovate with racing specific compression socks. Using the same graduated compression elastic commonly used in the athletic industry, the Sparco Compression socks feature a full Nomex construction for FIA approval. Sparco has designed the compression therapy to exert maximum pressure at the ankle, facilitating the flow of blood up from the feet and ankles. This helps reduce circulatory problems, alleviating fatigue and feelings of heaviness in the legs. Silicone printing has been added to the inside of the sock to help decrease slipping between the foot and fabric, resulting in increased pedal sensitivity.
